Abstract
A focus detection device, comprising an image sensor having pixel sections that subject light flux that has passed through a photographing lens to pupil division, and that are made up of pairs of pixels that respectively receive the light flux, and processors, wherein the one or more processors calculate degree of similarity between pixel signal rows that are positioned in a direction that is different to the pupil division direction, and are constituted by pixel signals of a plurality of pixels corresponding to at least one of the pairs, and if the degree of similarity is higher that a specified value, generate a spatial addition pixel signal by adding the pairs of pixel signals of the pixel signal row in a direction that is different to the pupil division direction, for each respective pair, and perform phase difference detection based on this spatial addition pixel signal that has been generated.
